Explorer and first superintendent of Yellowstone National Park, N. P. Langford once said, "A grander scene than the lower cataract of the Yellowstone was never witnessed by mortal eyes."
For a few short weeks a year, at the right time of day, a rainbow appears in the mist of the Lower Falls in the Grand Canyon of Yellowstone National Park.
Enjoy.
